What body process converts physical energy to electrical energy?
a. glycolysis
b. metabolism
c. photosynthesis
d. transduction

The correct answer of the question given is D.

There are four body processes mentioned in the question are named as glycolysis,metabolism,photosynthesis and transduction.

Glycolysis is the metabolic process in which glucose is converted to pyruvic acid with the release of ATP and NADPH.

Metabolism is a chemical process which includes the formation or dissociation of  chemical compounds.

Photosynthesis is the biological process in which food is prepared by plants by absorbing minerals, water from soil and carbon dioxide from the atmosphere in the presence of radiant energy [sun light] .

Transduction: It is the biological process in which any external physical stimuli is received and relayed from one part of the body to another part.During this process energy i.e stimuli is converted into electro chemical stimuli.
